    #POWERGEN 2017 Preview: Helping Power Generators Address the Skills Gap

    Author: Douglas Morris A January 2017 report from the U.S. Energy Department states: Workforce retirements are a pressing challenge. Industry hiring managers often report that lack of candidate training, experience, or technical skills are major reasons why replacement personnel can be challenging to find—especially in electric power generation. The wave of retirements has been talked about for years and...

    #POWERGEN 2017 Preview: Flexible Operations

    Author: Douglas Morris The new plants that are coming online today are already designed for fast start and flexible operations. With the changing generation mix, being able to move a unit is essential as fleets dispatch more renewables. But what about older plants that were designed to operate as baseload generation? Sometimes units must be mechanically retrofitted to be able to better participate in the market...

    #POWERGEN 2017 Preview: Microgrids and Controls

    Author: Douglas Morris Microgrids are collections of generating sources that are coupled to operate as one either connected to or disconnected from (islanded) the main power grid (sometimes called the macrogrid). Being able to independently provide one’s power is becoming popular with standalone entities like colleges or universities, military bases, and remote locations. Hawaii is embracing microgrids and has...

    Automating Combined-Cycle Power Generation Startups

    In combined cycle power plants : …the heat of the gas turbine’s exhaust is used to generate steam by passing it through a heat recovery steam generator (HRSG) with a live steam temperature between 420 and 580 °C. The condenser of the Rankine cycle is usually cooled by water from a lake, river, sea or cooling towers . Over the past decades, combined cycle power plants were built to handle base electrical...

    #POWERGEN 2017 Preview: HRSGs, Steam Attemperation and Tube Leaks

    Author: Douglas Morris We all know that today’s plants must cycle more; that’s just the expected mode of operation. Keeping plants online with the ability to cycle, particularly cost-competitive combined cycle units, is a focus for most utilities and avoiding heat recovery steam generator (HRSG) tube failures is a good place to start. These failures can be attributed to corrosion, thermal issues, and creep...

    Monitoring Your Medium Voltage Switchgear

    When I worked in the offshore oil & gas business many years ago, production platforms typically had low-voltage electrical systems running motors no larger than 480VAC. Over the years as the process sophistication grew and motors with variable speed drives replaced engine-driven compressors and other assets, the need for medium voltage systems (between 1KV and 35KV) grew. For most other industries with access to an...

    Model Predictive Control in Power Generation

    Model predictive control in power generation was the subject of a 2017 Ovation Users Group presentation by Emerson’s Ranjit Rao . Rajit opened comparing classical control with model-based control. In classical control, a proportional-derivative-integral loop is used with feedback. There is a setpoint, the actual process variable and the error or difference between the process variable and setpoint. Based on the...

    Simulation for Training and Engineering Applications

    At the 2017 Ovation Users Group conference, Emerson’s Bob Kerestes and Sheldon Willis gave an update embedded simulation in the Ovation system. Sheldon opened the presentation describing types of uses for simulators for training and engineering. For training simulators, simulations can range from simple tie-back models to high-fidelity models which simulate the dynamics of the running process. For high-fidelity...

    Generator Excitation 101

    Generators turn mechanical energy into electrical energy by moving electrical conductors in a magnetic field. Excitation creates the electromagnetic field to make this mechanical to electrical conversion occur. Emerson’s Rich Dennis provided a basics presentation on excitation control at the 2017 Ovation User Group meeting. Excitation control includes synchronous machine regulation, exciter, synchronous machine...

    Comprehensive Cybersecurity for Critical Infrastructure

    The electrical power generation and distribution industries, especially here in the U.S., have a long history in working to improve reliability and security. This history goes back to the establishment of the North American Electric Reliability Council (NERC) in the late 1960s as a response to a widespread blackout in the Northeastern U.S. NERC became the North American Electric Reliability Corporation (also NERC)...

    Continuously Monitoring Critical Electrical Assets

    One common thread with Industrial Internet of Things (IIoT)-based sensors is that they typically will replace periodic, manual measurements. We shared IIoT application examples in past posts of how business performance—in safety, reliability and efficiency—can be improved. The common thread is that continuous data streams from these IIoT sensors feed analytics applications, which can help spot & notify personnel of...

    Avoiding Dangerous Malware Infections

    The malware WannaCry/WannaCrypt has been all over the news recently. Since most of the operator and engineering workstations used in distributed control systems (DCSs) and supervisory control and data acquisition systems (SCADA) are PC-based, the question was naturally could these have been/or be impacted by this dangerous malware. I caught up with Emerson’s Jaime Foose . She noted that it is important to point...

    Improving Burner Control with Gas Chromatographs

    There once was a time for industrial manufacturers when they received fairly homogeneous supplies of natural gas that did not vary much in energy content. Here in the U.S. with the rapid increase in shale gas production as part of the overall energy mix, there is more variance. In a Power magazine article, Gas Chromatographs Offer New Technology for Power Plant Burner Control , Emerson’s Bonnie Crossland describes...
